The development and, generally, the life of being human develop through successive stages that have very special characteristics. Each of them is based gradually on the following stage. Nevertheless, there is no a unanimous agreement to determine how many and which are those stages. It is not possible either to be said when it begins exactly and when each stage finishes, because in the development they influence diverse individual factors, social and cultural. For that reason one says that each human being has his own rate of development.

Generally, it is considered that the stages of human development are the following:

1.Prenatal

2.Childhood

3.Childhood

4.Adolescence

5.Youth

6.Adulthood

7.Old age

•Zigótico period: One begins at the time of the conception, when the fecund spermatozoon to the egg and forms the ovum or zigoto. This it begins then to be divided and to subdivide themselves in cells and increases of size until forming the embryo, that at the end of the second week takes root in the uterus.

•Embryonic period: It lasts 6 weeks, in which the embryo is divided in three layers that are been different until forming the corporal outline of the diverse systems and apparatuses.

•Fetal period: It is the culmination of embryo. The fetus already has the defined form of a human being, who after being developed quickly during 7 months, leaves the maternal cloister in the act of birth.
